CheckBoxListCellData(javax.swing.Icon icon, java.lang.String text, java.lang.Object userObject, java.lang.String toolTipText)
A CheckBoxListCellData with an icon, a text label, and a tooltip; there is no checkbox.

_text

_isTextEnabled

protected boolean _isTextEnabled

This should be true if the list's text is drawn as enabled; false otherwise.

_isTextSelectable

protected boolean _isTextSelectable

This should be true if the list's text is selectable; false otherwise. Usually, you should allow the text to be selected even if the label itself is disabled. This at least lets the user know that the selection is acknowledged, but no action is permitted.

_icon

protected javax.swing.Icon _icon

The icon shown with the text. If null, no icon is shown.

_hasCheckBox

protected boolean _hasCheckBox

If true, then the cell renderer should include a checkbox; if false then no checkbox. The checkbox is a a tri-state checkbox. To set the checkbox to the third state call setCheckBoxState(null).

copyTo

Copies the internal state of this object to the specified copy. If copy is null, then this method should create a new instance of this class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.

Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this object's state was copied.

There is a standard implementation pattern for the copyTo method that helps avoid problems that arise when a Copyable object is subclassed. The pattern is:

The parameter passed into the copyToImpl method is the same type of this class. The responsibility of copyToImpl is to copy the state of this class through direct access of the fields. The copyToImpl method should not use getters and setters since these may be overridden, causing the state of this class to be incompletely copied.

target - The target object to which the state of this object should be copied. If target is null, then the copyTo method will return a new instance of this class.

Returns:

The object to which the state of this object was copied. If the target was non-null, then the return value is the same as the target object that was passed in; otherwise, the return value is a new instance of this class.
